I do understand why Corona development discontinued it.
Never seen a more horrible soft that Sketchup.
You obviously don't know it's power yet. We can do things at three times the speed what most designers on other platforms can't...
LOL ! :)
What is "fast" in SK?
That you need a plugin even for basic functions, wich most softs have integrated?
That you have to constantly group everything?
That it automatically splits intersecting lines & surfaces?
That it has only one viewport?
That it bools only one thing at a time?
That it has only a handful of export formats - and exports crappy?
That it slows down even strong PC, as soon as a scene grows bit?
That rounded shapes are facetted, except you fiddle around?
That you cannot even draw a freeform curve with proper control points?
I could list 100 more things here.
Dude, I´m an industrial designer with 15 years of working experience.
You say "I don't know the ... reeeeeeal power of SK... ".
Sounds like a student in the 1st semester.
SK is not "three times faster than other softs", as you naively claim.
It´s freaking slow, as soon as your work includes more than dragging and stretching some simple boxes.
